Welcome to KGMS!

The Kalamazoo Geological and Mineral Society (KGMS) is a friendly group of people that share an enthusiasm for geology. The purpose of the club is to further interest in gems, minerals, geology, paleontology, and the lapidary arts. Each KGMS member has their own unique interest but love sharing what they know with others. What ever your geological fascination you will find good company in the Kalamazoo Geological and Mineral Society.

Each meeting we cover club business, usually have a presentation or two, maybe some show & tell, talk about any trips coming up and then adjourn. Kids are welcome and will have their own activities during the meeting.
